Thanks for the input so far. I follow the "too American" vibe, but that is pretty much what I am going to be limitied to. The bolt pattern and offset are the same as most pre 80s rwd GM passenger cars. (ie Nova, Chevelle, Skylark, Monte Carlo, etc, ad naseum) Combine that with a maximum diameter of 16" and I am left with "street rod/muscle car" type wheels.
The wheels on the car now are replicas of the 84-? Corvette wheel. Does'nt get much more "American" than that!
I have been totally forgetting about "billet" type wheels though. Companies like Budnik, Colorado Custom, Weld Racing, and the like should have plenty of wheels that would fit. I am sure something will provide the right mix of retro/modern without looking like they came off a '32 Ford Roadster. The search continues!
